This is a diagram of a lightning protection for power supply device/patent.
Acronyms correct?
TVS Transient-voltage suppressor
MOV Metal Oxide Varistor
GDT Gas Discharge Tube
Fu1-Fu3 main protection fuses
L1, L2, L3, L4 decoupling components
2. Acronyms?
PE = Protective Earth (equipment side earth)
Lin = live in
Lout = live out
Nin = neutral in
Nout = neutral out
Any issues or potential problems with such a circuit?
Will TVS fail catastrophically if high voltage (via lightning) lasts for even a few seconds?
3. Fracturing or Fire damage to MOVs?
1. MOVs are prone to catching fire in cases of extended current surges.
2. How many surges can they handle?
Seems that No one knows until failure occurs, right?
Case in China (multiple return lightning strokes)
" multipulse lightning surge is often the driver for the temperature rise since it causes energy to accumulate in the MOV due to its long thermal time constant..leading thermal damage & cracking"
"GDTs can be damaged by extreme exposure to lightning. The typical failure mode is an increase in voltage at which the GDT conducts (or protects), or complete catastrophic failure for severe exposures"
Will this device/patent definitely protect sensitive electronic devices against overvoltage transients in normal mains voltage and repeated nearby lightning strike overload/ short circuit events?

"During shooting in Thailand, I was shocked by Daszak’s fast & loose with facts, his refusal to acknowledge his conflict of interest,& his denial of his gain-of-function res in collaboration with Wuhan lab"
You guessed right, i hope?
@janeqiuchina
She continued:
"I was equally shocked by Daszak’s constant self-promotion and how effective it was."
@janeqiuchina About the film:
"Blame: Bats, Politics & a Planet Out of Balance"
"Christian Frei seemed entranced by hero worshipping, apparently having lost all sense of objectivity & critical judgment. I felt strongly then, as I do now, that the film was a blatant piece of propaganda"
Bloody Hell, it's worse than even I imagined in my darkest nightmares about #scamdemia.
Time to spend some of this tax money on local electronics, biological, ecological, IT, optical, chemistry, engineering & physics labs run by local amateurs for the benefit of our communities?
Short 🧵on Primer & PCR Test issues (Pangolin Covs)
1. The key issue with pangolins and Pcovs is that:
It was discovered that the standard PCR tests used in 2020, and often still used, failed to actually detect many of the betacoronaviruses generously hosted by the pangolins.
2. Unless
The samples are retested with bespoke primers & more accurate PCR tests available now,
We will not know exactly whIch Pangolin (or bat) coronaviruses were hosted by Pangolins at WIV & elsewhere pre-pandemic.
However, "they" (I will name who they are later) should, and perhaps in the future, may retest the stored samples at WIV, IPB, SCAU AND GIABR, to clarify the question of which coronaviruses were present in their pangolin samples.
2. May have been for research and commercial purposes, but they were caught bang to rights.
"LIU initially stated that he did not know what the materials were and that someone must have put them into his bag"
3. When asked why someone would put them into his bag, LIU stated that he did not know, and that maybe he had accidentally put the materials there. After further questioning, LIU acknowledged that the materials were different strains of the pathogen Fusarium graminearum
